RockShox Charger 3.1 RC2 Damper Upgrade Kit

The 3.1 upgrade expands the damping range, specifically offering less low-speed compression in the open setting for a smoother feel and more support in the high-speed closed setting for better traction. It essentially makes the fork more sensitive to small bumps while keeping it stable on bigger hits.

This kit is compatible with 2023 and newer Lyrik and Pike models, as well as ZEB models from 2021 onwards. It is also compatible with 2024+ BoXXer D1+ forks, but you should always verify your specific fork's model year and chassis type before purchasing to ensure a proper fit.

The kit includes the necessary Head Valve Tool to assist with installation, which is a significant help. However, you will still need standard suspension service tools, such as a torque wrench, socket set, and suspension oil, to complete the swap properly.

If you are comfortable performing a standard lower leg service or damper swap on your fork, you can likely handle this installation. If you are not experienced with internal suspension maintenance, it is safer to have a professional mechanic install it to ensure the damper is bled correctly and functions safely.

Yes, this kit replaces the internal piston assembly and tuning shims of your current damper. It restores the tactile, precise feel of your compression adjustments, ensuring your high-speed and low-speed settings are responsive and accurate again.
